Explanation
The project MCP confinement fallback lacks focused regression coverage.
confineForMcpWrite("project")usesproviderRef.deref()?.cwd ?? getWorkspacePath()atsrc/services/mcp/McpHub.ts:659-664, but every added project-write test setsmockProvider.cwdto/mock/workspace(src/services/mcp/__tests__/McpHub.spec.ts:1025-1110). No MCP test configures an unavailablecwd, supplies a distinctgetWorkspacePath()value, and asserts that value reachessafeWriteJson. A regression in this fallback would pass the current tests.Resolution
Add an MCP call-site test that leaves
providerRef.deref()?.cwdunavailable, mocksgetWorkspacePath()to a distinct workspace path, performs a project timeout, deletion, or allowlist write, and asserts thatsafeWriteJsonreceives the fallback asconfineTo. Keep the existing explicit-cwdand global-unconstrained tests.

Explanation
The changed project MCP write path still permits a confinement escape.
McpHub.updateServerConfigandupdateServerToolListpass project settings throughsafeWriteJsonwithconfineTo, butsafeWriteJsonpublishes with path-basedfs.renameinsafeWriteTextafter its final confinement check. If a concurrent process replaces.rooor another ancestor with a symlink after that check, the write can temporarily create the MCP settings file outside the workspace before the post-commit check unlinks it. The MCP configuration can contain credentials inenvorheaders(McpHub.ts:97-105, 113-136). The changed regression test explicitly drives this ancestor-swap window (safeWriteJson.test.ts:897-939), confirming the unsafe publication path. This is a concrete changed path that can leak project MCP secrets outside the declared scope.Resolution
Make confined publication use pre-opened directory handles with no-follow semantics, such as a native openat/renameat helper, so staging and commit cannot re-resolve swapped ancestors. If the runtime cannot provide that guarantee, fail closed before publishing for every
confineTowrite. Add an integration regression that performs a project MCP credential write during an ancestor swap and verifies that no bytes are created outside the workspace, including no transient observable file.
Full details: Lifecycle Resource Cleanup
-
Explanation
The changed
safeWriteTextlifecycle leaks backup files after a successful commit. Whenbackup: trueand the finalfs.unlink(backupPath)atsrc/services/file-safety/safeWriteText.ts:596-603fails, the code swallows the error and resolves. No retry, ownership, warning, or later cleanup handles the retained file.safeWriteJsonalways delegates withbackup: true, so a transient permission or filesystem error during cleanup can leave one private backup per write. The added tests explicitly accept and verify this orphaned-backup outcome.Resolution
Do not silently resolve with an unowned backup. On successful commit, handle backup-unlink failure with a tracked retry or cleanup mechanism. At minimum, report the retained path through
onWarningand register it for a later cleanup pass that removes it.

awaiting-author
onWarning is documented as the sink for non-fatal safety notices, but delivery was not isolated from the write: an onWarning callback that threw propagated to the outer failure handler before fs.rename, turning a non-fatal notice into a failed save. The warn binding now catches callback failures and logs them. The restore-failure notice is routed through the same binding so a caller supplying onWarning receives it. Same fix as the u6 unit, kept aligned across the series. Local: safeWriteText 58/58 green; eslint clean, no suppression growth.
proper-lockfile creates ${lockKey}.lock beside the lock key, and the key is the
symlink referent. A repository that plants .roo/mcp.json -> ~/.ssh/config
therefore made a confined write create a lock directory OUTSIDE the declared
scope, and when that directory was not writable the caller got a
lock-acquisition error after up to five retries instead of
ConfinedPathEscapeError. The confinement check now runs on the lock key before
acquireFileLock and is repeated on the resolved publish target inside the lock
(a peer writer may have moved the referent in between); both checks share
_assertWithinScope so they canonicalize identically.
Ported across the file-safety unit series so every unit that declares a scope
carries the same guarantee (same fix as fws/u3-observation-completeness).
Series alignment for the two review findings fixed on fws/u6-apply-patch-wiring: 1. safeWriteText's warn wrapper could not catch a rejection from an async onWarning sink - TypeScript accepts a value-returning callback where a void one is expected - so the rejected promise was left unhandled, which under Node's default mode can end the process after a write that already succeeded. The wrapper now attaches a catch handler without awaiting (awaiting would let warning delivery delay a committed write, or stall it on a hung sink) and reports the rejection through the fallback sink. 2. safeWriteJson created the target's parent directory BEFORE the preflight confinement check, so a confined write to an out-of-scope path with a missing parent still created a directory outside confineTo. resolveLockKey and the check need no directory to exist, so the order is now lock key, confinement, mkdir; the in-lock check on the resolved publish target stays.
…ith doUnmock - safeWriteText.integration.spec: the backup:true case bails out in the backup step (copyfile over a directory), so the commit rename never runs and a regression in commit-failure cleanup would pass. Added the backup:false case, which is the shape that reaches Step 4: the rename of the staging file over the target directory fails and the staging file must be cleaned up. - safeWriteJson.test: the finally blocks removed a vi.doMock registration with vi.unmock, which vitest hoists to the top of the file, so the cleanup did not undo the registration where it was written. Both sites now use vi.doUnmock, the non-hoisted counterpart. Verified the two paths are distinct by calling safeWriteText against a real directory target: backup:true fails at copyfile, backup:false fails at rename of the staging file. Local: 29 passed / 4 skipped across the two specs; eslint clean on both files.
Task.ts initializes the registry per Task, but nothing read it off a real Task: the registry tests exercise standalone instances and ReadFileTool's spec injects its own double, so the wiring itself was unverified - a Task that never built a registry, or shared one across Tasks, would pass every existing test while silently dropping read observations. The new test constructs a real Task and asserts observationRegistry is an ObservationRegistry, that a second Task gets a different instance, and that an observation recorded on one Task is invisible to the other (parent and subtask authority over a file must stay separate). Local: Task.dispose.test.ts 15 passed; eslint clean; no new tsc diagnostics in this file.
Security Boundaries: safeWriteJson resolves the publish target through realpath before staging beside it, so a repository that ships .roo/mcp.json as a symlink to a file OUTSIDE the workspace has that outside file replaced as soon as the user edits a project MCP setting, deletes a server, or toggles tool always-allow. The three project-capable write sites passed no confinement option, and the base implementation renamed the link itself, so the external write is introduced here. confineForMcpWrite(source) returns the provider cwd (falling back to getWorkspacePath) for project writes and undefined for global ones - global settings live in the user's own settings directory, which is deliberately not confined. All three sites now pass it, so the write fails closed with ConfinedPathEscapeError instead of touching the referent. This is the same change as 256091d on fws/u3-observation-completeness (Zoo-Code-Org#1912); the unit branches are not cumulative, so every branch that carries the writer needs its own copy. Regression Evidence: the per-Task registry now fails closed on teardown too - disposeOnce() clears it, so a disposed Task still reachable through a parent/subtask reference cannot hand a token captured before teardown to a guarded write. Two McpHub tests pin the call sites (a project-scoped allowlist write carries confineTo = workspace root, a global one does not) and a Task.dispose test pins the clear. The two-real-Task registry test added in 87986e9 already covers the distinctness the checklist row asked for. Local: vitest McpHub + Task.dispose 89 passed. Negative controls: helper mutated to return undefined -> project confine test fails; clear() commented out -> disposal test fails; both restore green. tsc --noEmit 50 errors before and after the change (unchanged branch baseline). eslint 0 errors / 0 warnings on all four files, no suppression entry added or increased.
…every MCP confine site Lifecycle Resource Cleanup: disposeOnce() cleared the registry, but a read that was already awaiting fs.readFile when disposal began resumed afterwards and recorded the file again - the disposed Task was authoritative once more, and it kept doing the new post-read stat work for a turn that will never be acted on. ObservationRegistry.close() now drops the entries AND refuses later observations, Task.disposeOnce() calls close(), and both ReadFileTool paths skip the post-read stat + observe work when task.abort is set (checked before the awaited stat, not after it). Regression Evidence: the confinement fix touched three call sites but only toggleToolAlwaysAllow was pinned. updateServerTimeout and deleteServer now have a project case (confineTo = workspace root) and a global case (confineTo undefined) each; the connection double is shared at describe scope so all four sites use one typed fixture. safeWriteJson is mocked in this file, so a lower-level writer test cannot see a missing MCP argument - each call site has to be pinned here. Tests: 2 closure tests (close drops entries and reports closed; observe is a no-op after close), 2 aborted-task tests (native and legacy path record nothing), 4 call-site confinement tests, and the disposal test extended to assert the registry stays empty when a late observation arrives. Local: 203 passed across readFileTool, McpHub, Task.dispose and observationRegistry. Negative controls, each mutate -> test fails -> restore -> passes: ReadFileTool guard neutered, ObservationRegistry closure guard neutered (fails both the registry spec and the Task disposal test), and close() downgraded to clear() (fails the disposal test). tsc --noEmit 50 errors before and after (unchanged branch baseline, 0 in touched files). eslint 0 errors / 0 warnings across all 8 touched files; no suppression entry changed.
The abort guard sat before the post-read fs.stat, so a cancellation that lands while that stat is in flight still recorded an observation - for a run that will never act on the read, and into a registry that disposal has already retired. Both paths now re-check task.abort after the await and before observe(); the read itself still answers the model. Two tests flip task.abort inside the pending post-read stat, one per path, and assert observe() was never called and the registry stayed empty.
Port of the Zoo-Code-Org#1917 fix into this unit: the unit branches are not cumulative, so this branch carries its own copy of safeWriteText's lock-key helper and the same defect. canonicalDirKey() canonicalized only the immediate parent and fell back to that literal spelling on ENOENT. A writer whose parent directory already existed canonicalized through a symlinked ancestor (or a Windows short name) while a writer racing to create the same directory got the literal path, so the two took different locks for one file and a read-modify-write lost one side. It now walks up to the nearest ancestor that exists, canonicalizes that, and re-joins the missing components; a realpath failure that is not ENOENT is propagated instead of being papered over with a key that may be wrong. Identifiers and comments are kept identical to the other units so the merge resolves trivially.
… the write A defect reported on a sibling PR in the base repo: the backup destination is named before the copy runs, while the rollback cleanup keys off a flag that only becomes true once the copy succeeded - so a copyFile that fails after creating the destination leaves a half-written .bak beside the target forever. This branch does not have that shape. The whole backup creation (seed open with "wx", copyFile, chmod, fsync) is wrapped in a catch that unlinks the destination and clears backupPath before rethrowing, so the cleanup keys off the attempt rather than off the success. What was missing is coverage for the exact case the report describes: copyFile failing with the destination already created. Only the fsync-failure variant was tested. No production change. Negative control: deleting the cleanup unlink inside that catch fails exactly two tests - this one and the existing "a failed backup flush is reported and leaves no partial backup behind" - and restoring it leaves the file byte-identical.
No source change. CodeRabbit's change_assessment_commit for this PR has been frozen at 5596f3a since 15:30 across three heads (949c263, f1fb1b2, 7dec01b): three accepted "@coderabbitai full review" requests (18:42:03, 20:02:18, 20:19:42) each re-rendered the summarize against the OLD assessment and produced no review object at head, while the same pool produced a real at-head verdict for another PR minutes later. The auto-review that a push schedules recomputes the assessment for the new head, which the manual request does not.
Pre-merge table row "Regression Evidence" (ReadFileTool.ts:220-250, 828-890):
the native and legacy successful-read tests now count the fs.stat calls that
match - correct path AND { bigint: true } - instead of relying on membership,
which the read path's plain directory-check stat satisfies on its own. The
counted bigint stats must bracket the read (one before, one after), and the
plain directory-check stat must stay the only stat without options. In both
abort-before-post-stat tests the pre-read observation stat is still counted
(1, not 0) and placed before the read, while the post-read bigint stat must
never appear.
Load-bearing proof, measured per mutant with the full spec:
- bigint:true -> false at the native pre-read stat: reds exactly the native
success + native abort tests (2).
- bigint:true -> false at the native post-read stat: reds exactly the native
success test (1).
- legacy pre-read / post-read: mirror images (2 and 1).
- abort guard removed at each post-read site: reds exactly its abort test
(1 each). All six mutants restored byte-for-byte (sha256 verified).
Inline thread (McpHub.spec.ts): the global allowlist test picked the first
safeWriteJson call whose path contains "mcp", which can be the
default-creation write getMcpSettingsFilePath makes when the settings file is
missing - it never passes confineTo, so a confinement root added to the real
allowlist write would go unnoticed. The test now names the exact call: every
write to the settings file (endsWith mcp_settings.json) is checked, matching
the timeout and delete tests. Controls: adding confineTo to the production
allowlist write reds exactly this test; with a decoy mcp-named write first,
the old find went red on the decoy while the fixed matcher stayed green
(77/77), proving the selection names the right call.
Gates: readFileTool.spec 99 passed; McpHub.spec 77 passed; eslint
--max-warnings=0 clean on both files; eslint-suppressions.json untouched.
The repo-wide prettier check added on main (commit 667ff58, run on the merge commit) flags exactly three lines inside this PR's own diff: one execute call in readFileTool.spec.ts and two safeWriteJson filters in McpHub.spec.ts, all introduced by this branch's earlier commits (measured with git blame at the previous head). Each line exceeds printWidth 120 and prettier wraps it; nothing else changes. Pure-formatting proof, per the ratified criteria: byte equality after removing whitespace AND commas holds for both files (McpHub 86088 == 86088 whitespace-only; readFileTool 72964 == 72965 with the single added trailing comma from the call wrap). No file outside this PR's diff is touched. prettier --check now exits 0 on both files in the CI view (LF content, root config); both specs pass (99 and 77) and eslint --max-warnings=0 is clean.
…ix unit files The compile job starts with pnpm format:check (prettier --check . added to main by commit 667ff58), and it evaluates the merge commit. CI listed exactly these six files as dirty; all six are inside this pull request's own diff and every offending line traces to commits of this branch (verified with git blame at the previous head). Content is prettier 3.8.4 output only. Proof: for each file, the blob before and after are byte-equal after removing all whitespace characters and all commas (the formatter's reflow adds and removes trailing commas); the only other delta is one redundant pair of grouping parentheses around an arrow-function conditional body in safeWriteText.spec.ts, which prettier itself removes. No token other than whitespace, commas, and that paren pair changed. No behavior change; no production semantics touched.
The Windows platform-unit-test job failed test:misc on the merge tree: integrations/misc/__tests__/indentation-reader-unicode.spec.ts, added to main by pull 1960 (commit a101c61), asserts the reader result with toEqual over the exact five-key object. This unit adds hasClippedLines to readWithSlice results and to both readers' error returns, so three of those assertions received a sixth key on the merge commit. The offending expectations came from main, not from this branch; the fix lands in this pull request's own diff because the gate runs on this pull's merge commit. The preceding merge of upstream main is what lets this edit land as a modification: without it the file exists only on main and the same edit would surface as an add/add conflict and make the pull dirty. Assertions updated to the shipped contract: hasClippedLines true for the two clipped-line slice results, false for the empty-input slice result and for both reader error returns. The readWithIndentation success results do not carry the field and their assertions are unchanged. Negative control: replacing the produced value with undefined at the success site reddens the two true-cases, and at the error sites reddens the error test; restoring turns the file green (28 passed).
Both main and this branch added the same "import type { Task } from
../../task/Task" line to readFileTool.spec.ts at different positions, so
the textual merge kept two copies and the file failed to collect:
TS2300 Duplicate identifier 'Task' (vitest reported "Tests no tests").
The Windows job never reached this project because test:misc failed
first, so CI had not surfaced it yet.
Kept main's copy (the line main owns) and removed this branch's copy.
Spec passes after the fix: 106 tests green.
…e spec Both main and this branch edited readFileTool.spec.ts, and the merged file contains 94 explicit-any occurrences while the merged eslint-suppressions.json still declared 96 (the byte-identical file on the pull's merge ref has the same staleness; CI had not reached the Lint step because the compile job died earlier). The suppression service exits 2 on suppressions that no longer occur, so the merged tree's lint step would have failed. Measured with eslint itself (prune run reported 96 -> 94 for this file only) and applied as a one-line byte-exact edit; the file keeps its TAB indentation and trailing newline. The count decreased, never increased. Full src lint now exits 0 with --max-warnings=0.
Both confinement checks in safeWriteJson tested options?.confineTo for truthiness, so a caller passing "" skipped both gates and the write followed any symlink with no scope check. The value occurs in practice: McpHub.confineForMcpWrite falls back to getWorkspacePath(), which is "" while no workspace folder is open, so a project-scoped MCP write ran unconfined even though the caller declared a scope. Confinement is now decided once, up front. _declaredScopeRoot returns undefined only when confineTo is absent, rejects a declared root that is empty or whitespace-only with a ConfinedPathEscapeError naming the declared root, and both confinement checks key off the single derived presence value instead of separate truthiness tests. A declared-but-empty root fails closed before the lock key is resolved, before the lock is taken, before any directory is created, and before anything is staged. Tests pin the empty-string case: the rejection names the declared empty root, the write does not proceed, the target parent directory is not created, and a whitespace-only root fails the same way.
confineTo was documented as refusing a write "that a planted symlink would land somewhere else", which reads as containment for the whole write. It is not. Both confinement checks decide from the final component as it resolves at their own instant, and publication is path based - the parent-directory creation and the commit rename both take a path - so an ancestor directory replaced by a link in the window between the last check and the rename redirects the publish. Measured outcomes of that window, on both platform shapes: - the swapped-in directory already has a file at the target name: realpath resolves the target onto it, the staging identity guard rejects the commit with StagingPathError, and nothing is written on either side; - it does not: realpath and lstat both report ENOENT, resolvePublishTarget falls back to the alias spelling, and the rename follows the swapped ancestor, publishing OUTSIDE the declared scope. Handle-relative no-follow publication (openat/renameat over a directory fd) would close the window; this runtime exposes neither call, so the claim is narrowed here instead of being made true. No new option and no second confinement mechanism: the checks, their order and their outcomes are unchanged. The credential-carrying call sites keep the control and state their own limit in the comment on the helper they call: the case a committed tree can actually plant is a link at the settings file itself, which confineTo does refuse, so dropping the option would give up a refusal that works today in order to close a window no unit can close in this runtime. Two tests pin the limit as an executable contract, one per outcome, with the ancestor swapped from the merge callback so it moves inside the window rather than hopefully so. Against a production that honoured the old claim - a confinement re-check at the publish - exactly those two tests are red (2 failed / 29 passed / 4 skipped); against the shipped production they are green, because this change narrows a claim and not a behaviour. Per-call-site mutants of the control each redden only the test that names that call site (pre-lock check 2, declared-but- empty root 3, each McpHub confineTo 1). Local: safeWriteJson, safeWriteJson.lockKey, safeWriteText, safeWriteText.integration and McpHub together 177 passed / 4 skipped; eslint --max-warnings=0 clean on all three files with no suppression drift; tsc --noEmit 137 errors, none in a touched file (junction-donor baseline); prettier --check clean on the three files after the CRLF to LF rewrite. See tracking item 6104592203.
…rved The Security Boundaries pre-merge row reports that safeWriteText commits a replacement when the Windows DACL capture fails - it only warns, although the replacement may inherit different access rights - and that the same warn-only shape covers a DACL restore that fails after the commit rename. A project .roo/mcp.json with restrictive ACLs can hold MCP env or header secrets, so a publish that silently widens who can read the file is not a save the caller can trust. Fail closed for an existing target whose DACL cannot be read or preserved, on the shape the chain's earliest unit already ships: - DaclInspectionError (phase "save" | "inspect") is thrown in step 2, before the commit rename, when icacls /save fails or the target exists but its access rights cannot be checked. Nothing is published, so the target keeps its content and its rights, and the failure handler still releases the staged file and this write's own staging directory. - DaclRestoreError is thrown in step 5 when the saved dump cannot be put back, so no caller can observe success for a publish whose DACL was not preserved. - The failure handler keeps the backup copy for a DaclRestoreError instead of removing it: that copy is the only artifact still carrying the access rights of the file the publish replaced, so deleting it would destroy the recovery path for exactly the fact the error reports. Its path is named through onWarning, which now carries only that leftover notice. Tests pin each point at the primitive: the refusal with its phase and target path, no rename and no warning for a write that did not happen, cleanup counted once, the restore failure as an error with the dump still unlinked, the backup copy retained and named, and the caller-staged shape safeWriteJson hands in. Negative controls: four mutants, one per changed production call site, each reddening only the tests that name that behaviour, plus a run of the new tests against the pre-fix production file (10 red, 55 green).
Zoo-Code-Org#2038 turned @typescript-eslint/no-unused-vars back on in src and removed the tree's dead bindings. Replaying this unit onto that main exposed the bindings this unit's own code left unused once main's deletions landed: drop the ReadFileTool/SafeWriteTextOptions/lockfile imports and the never-read committed flag, prefix the four write-path destructurings whose value no assertion reads, and restore the safeWriteJson import main pruned (main had no reader; this unit's McpHub tests do). No behavior change: 357 tests green across the unit's specs, eslint clean, tsc adds no new errors beyond the pre-existing local donor-package drift.

Learning: For MCP write-confinement reviews, src/services/mcp/__tests__/McpHub.spec.ts mocks both safeWriteJson and fs/promises. Test caller forwarding of confineTo at this layer for toggleToolAlwaysAllow, updateServerTimeout, and deleteServer, including project and global cases. Real-filesystem confinement enforcement belongs in src/utils/__tests__/safeWriteJson.test.ts. Do not require duplicate real-writer coverage in the mocked McpHub spec when the writer layer already covers the relevant behavior.

…k key Security Boundaries: safeWriteJson's confinement check decides the target as it resolves at check time; publication takes a path and the OS re-resolves the tree at commit time, so an ancestor directory replaced by a link inside that window published mcp.json outside the declared scope. The write now re-resolves the published path after the commit: if the bytes landed outside, the escaped file is removed and the write reports ConfinedPathEscapeError (fail closed + undo). The executable contract test flips from documenting the escape to requiring the refusal; the clash outcome still stops earlier via StagingPathError, so the two remain tellable apart. NC: disabling the post-commit re-check reddens exactly the flipped test. Persistence Integrity: withFileLock locked the RAW path while safeWriteJson locks the canonical key from resolveLockKey, so a task-history deletion through withFileLock and a merge write through safeWriteJson watched different lock files on symlinked paths - the compound read-modify-write was not atomic against deletion. withFileLock now takes the same canonical key (one shared lock-key function) while the operation still receives the caller's own path, so the unlink keeps alias semantics. New spec pins both halves: the locked key equals resolveLockKey(alias), and the operation sees the alias. NC: reverting to the raw key reddens exactly the key test. safeWriteJson.test failure set identical to baseline (12 pre-existing local Windows DaclRestoreError flakes; CI authoritative).

This PR makes the read side honest about what it saw. Each read brackets itself with a bigint
fs.statpair and records an observation of the target only when both tokens match - so a file that changed underneath the read is never recorded as fully seen - and the record says whether the view was complete. "Lines clipped in this view" and "lines omitted from this view" become two separate notices instead of one conflated message.Why it matters: a slice, a truncated read, or a lossy indentation view must never authorize a full-file replacement later. This unit is what makes the guard's "was this write earned by a read?" question answerable. It is the fourth of nine PRs for epic #1375 (chain tracked on #1991).

ReadFileToolbrackets each read with a bigintfs.statpair and observes the target only when both tokens match, recordingcompleteso a slice, truncated, or lossy view never authorizes a full-file replacement. A stat failure leaves the target unobserved and never fails the read.indentation-readerseparates "lines clipped in this view" from "lines omitted from this view"; the native and legacy read paths report the two notices independently.Taskowns a per-instanceObservationRegistry;Task.disposeOnce()retires it so a read that resumes after disposal cannot repopulate it, and both read paths skip the post-read stat and observation work oncetask.abortis set.confineTo(the provider cwd, falling back togetWorkspacePath()); global writes stay unconstrained by design. The unit branches are not cumulative, so each branch carrying the writer needs its own copy of this port.Why the diff looks bigger than the change: the chain is non-cumulative - this branch is based on
mainand carries its own copy of the earlier units' content, which the GitHub diff shows as context.Review focus:
src/core/tools/ReadFileTool.ts,src/integrations/misc/indentation-reader,src/core/task/Task.ts(dispose path), and the specs named in the Test Procedure.Test Procedure
From the repository root, with dependencies installed:
pnpm --dir src test -- core/tools/__tests__/readFileTool.spec.ts integrations/misc/__tests__/indentation-reader.spec.ts services/mcp/__tests__/McpHub.spec.ts core/task/__tests__/Task.dispose.test.ts core/task/__tests__/observationRegistry.spec.tsExpected: 203 passed across the suites this unit touches (readFileTool 97, plus indentation-reader, McpHub, Task.dispose and observationRegistry). Then
pnpm --dir src exec tsc --noEmit- clean.Manual check: point a workspace at a repo that ships
.roo/mcp.jsonas a symlink to a file outside the workspace and confirm a project MCP setting write is refused.Environment: Windows 11, Node 20, unit layer only.
